2 Claims. 1

The present'invention is shown applied to the mounting:eofaelectricalf,cendensershat have tubular non-metallic shells, although in certain ofits aspects the invention isfapplicable to other types of condensers andthe casings therefor and to otheizielectrical units suchsasbatteries',finduc tion coils,.resistors.and the like.

.object of the. inventionzis nto providey a condenser .arid-f.,mountingappurtenances therefor, Inadeof fewv parts andoflowicostfwhich shall beeasy toinstall andwhichshall require a minimum of available space atthe'underside of chassis or other mounting plate or base.

Another object is to provide a structure of the above` type,` that willreadily accommodate and securely mount a'condenser'serving asreplacement upon a chassis or other support designed for accommodatingmore elaborate condenser mounting appurtenances.

In the accompanying drawings in which are shown one or more of variouspossible embodiments of the several features of invention,

Fig. l is a View in longitudinal cross-section through the mountedcondenser,

Fig. 2 is a fragmentary transverse sectional view taken on line 2-2 ofFig. 1,

Fig. 3 is a transverse sectional view taken on line 3--3 of Fig. l,

Fig. 4 is a fragmentary View of a modification, and

Fig. 5 is a bottom plan view of the condenser showing a slightmodification in the chassis plate.

Referring now to the drawings, the con-denser desirably comprises anopen ended cardboard tubular container IU, desirably cylindrical, withinwhich is mounted the active condenser element II which may bey of anyconventional construction, such as a roll incorporating the two metalfoil electrodes and the associated sheets of dielectric (not shown). Thecondenser element is mounted in protected position within the tube bycompletely imbedding the same in filler, desirably a mass of congealedor hardened plastic I2 such as wax, pitch, or the like, which adheres tothe inner wall of the tube, which extends flush with one end of the tubeas at I3 to constitute a closure or plug and which does not quite extendto the opposite end of the tube'as shown at I4.

The condenser has a pair of flexible terminal leads I5 and I6 which maybe riveted as at r to the respective electrodes, said leads protrudingas shown beyond the pitch, wax, or other iiller.

A cross brace, desirably of metal, and preferably in the form of a yokeI1 extends within tube I0 across the open end thereof, its arms I8 andi9 engaging diametrically yopposite parts -of theinner wall of the tube,and being-preferably riveted thereto at 2li to secure the yoke in place.

Desirably the yokeis slightly countersunk with respect to the extremityof ithe tube and aiiber disk 2 I is frictionally-cr adhesively retainedVwithin the rimof the tube so as lto expose through the end of the tubethe mid portion of the yoke and a'pair of segment shaped openings v-22through which the respective iiexible leads I5 andv I6 may protrude inspaced relation straddl-ing-'the yoke.

A clamping bar' 2li isprovided which maybe of alength but slightlygreater than the diameter oi the chassis hole and has a raised orindented mid portion and lateral wings 25. -A screw l2 3, ax-

i'ally oi' the'tube, connects the middle of' the vyoke and the middle ofthe clamping bar 24. Desirably the shank of the screw is threaded intoyoke II as shown in Fig. 1 and its head exerts pressure against theclamping bar. Alternatively, as shown in Fig. 4, a screw shank 23 isrigid with the yoke, and nut 23a threaded upon the lower end thereofexerts like pressure.

As shown in Fig. 1, the unit is readily mounted by superposing the sameover the chassis plate or other mount or base 2'6, then applying thescrew 23 over which the clamping bar 24 has first been placed, lthrougha corresponding aperture 2l in the chassis plate and then threading itinto the yoke I'I until .the wings 25 of the clamping bar are tightlypressed against the under face of the chassis plate. The indented orraised mid-section of the clamping bar extends diametrically across andinto aperture 2l and thus serves to center the unit with respectthereto. The pressure transmitted through the screw presses the rim 28of the condenser shell against the chassis plate for security of mount.The flexible leads I5 and I6 extending through the segment shapedopenings 22 laterally of the yoke II pass through the aperture 21 in thechassis plate and protrude beyond the clamping bar 24 for electricalconnection.

Instead of the single aperture 21 in the chassis plate through whichextend the mounting screw as well as the terminal leads, there may beprovided three smaller apertures 30, 3I, and 32, as shown in Fig. 5, onefor the screw 23, and one for each of the flexible terminal leads I5 andI6.

It will be seen that the construction is quite inexpensive, yeteffective in use. It has the further advantage that the mountingappurtenances extend but a small fraction of an inch below the chassisplate, so that it is adapted for compact installation Where the greaterbulk of more elaborate terminal instrumentalities could not beaccommodated.

The construction of the present invention is useful as replacement forthe more elaborate condenser heretofore employed. No adaptation or othermodification in the chassis or other support is required for thispurpose, as the same hole 21 in the chassis used for the familiar mountsserves to accommodate the simplied mount of the present invention.

.As many changes could be made in the above construction, and manyapparently Widely different embodiments of this invention could be madewithout departing from the scope of the claims, it is intended that allmatter contained in the above description or shown in the accompanyingdrawings shall beinterpreted as illustrative and not in a limitingsense.

Having thus described by invention, what I claim as new and desire tosecure by Letters Patent of the United States is:

1. A device for mounting an electrical unit including a shell open atone end thereof upon a chassis having a mounting aperture therethrough,said device comprising a cross brace within said shell at the open endthereof and rigidly affixed thereto, a screw threaded into said crossbrace and extending through said mounting aperture, a clamping bar aboutthe shank of said screw and disposed on the opposite side of saidchassis from said unit, said clamping bar extending over a portion ofsaid mounting aperture to provide access therethrough to said unit, saidcross brace and said clamping bar serving as a mounting clamp foraifixing said unit upon said chassis when the screw is tightened inplace.

2. A device for mounting an electrical unit including a shell upon achassis having a mounting aperture therethrough, said device comprisinga cross brace within said shell at one end thereof and rigidly affixedthereto, a screw threaded into said cross `brace and extending throughsaid mounting aperture, a clamping bar about the shank of said screw anddisposed on the opposite side of said chassis from said unit, saidclamping bar extending over a portion of said mounting aperture toprovide access therethrough on either side thereof to said unit, saidclamping bar having an indented midsection coacting with said mountingaperture and serving to center the unit with respect to said aperture,said cross brace and said clamping bar serving as a. mounting clamp forafxing said unit upon said chassis when the screw is tightened in place.
